The main cause of global warming is nearly a century of human heavy use of fossil fuels,large amount of greenhouse gas emission; the burning of coal,natural gas,a large amount of greenhouse gases; wanton cutting of forests,making the ability to absorb carbon dioxide and lead.
The consequences of global warming,will lead to the redistribution of global precipitation,glaciers and permafrost to melt,sea-level rise,endangering not only the balance of the natural ecological system,but also a threat to the human food supply and living environment.A few days ago,polar bears are beginning to cut one another's throats,Hierro Island lizards due to climate variation on the verge of extinction,warm winter disrupted flowering,bloom all over Japan cherry blossom in advance; because the warm climate Moscow warm winter,bears suffer not hibernating; France this year suffered a warm winter,birds species were significantly reduced in number.The majority of our region also appeared in " warm winter ".Climate warming will make our country main crop breed to change,will cause water shortages and increased mortality.People have to pay for climate warming is more and more heavy price.
When I was informed of these circumstances,the mood is heavy.Chairman Mao taught us " the world is yours,is our,but in the final analysis is your." At present,I,as a ordinary middle school students,and to the world difficult problem do?From now on,from daily bagatelle,lay a good foundation for tomorrow.To save energy,protect environment is the key.Nowadays,some places due to depletion of energy while facing the crisis of survival,but in some places it in a tremendous waste of.We want to from their own work,to develop good saving habits,to save every drop of water,every degree of electricity.See others waste,to actively prevent.There is a need to identify effective methods,to solve the problem.This is not only a scientist things,but every man.As a middle school student,we can only grasp the rich scientific and cultural knowledge,in order to solve this problem is to make a great contribution to.
All human beings are of concern to climate warming,let the world is full of alertness and consciousness.To save energy,protect environment,let us work together..
